DRAF'I -RIGGING FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent N 0. 718,563, dated January 13, 1903.

fipplication filed October 26, 1901. Serial No. 80,112. (No model.) I

To aZZ'whom it may concern.-

Be itknown that I,-HENRY BRUNs,a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Draft-Riggin g for Railway-Oars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a draft-rigging for use on railway-cars, the principal object of the invention being to so construct a draftrigging that the draw-head thereof is capable of having swinging motion imparted thereto by movement of the truck-bolster of the car, so that the draw-head will move in correspondence to said bolster when the car-truck is rounding curves, thereby preventing liability of the draw coupler-heads being disengaged from each other. 7

My invention consists in features of novelty hereinafter fully-described, and pointed out in the claims.

Figure I is a top or plan view of my rigging. Fig. II is a vertical longitudinal sectional View taken on line'II II, Fig. I. Fig. III is an enlarged detail perspective view of one of the filler-washers applied to the draft-rod carriers. Fig. IV is an inverted view of the rigging. Fig. Vis an enlarged vertical sectional View takenon line V V, Fig. IV. Fig. VI is a detail sectional view taken on line VI VI, Fig. V. Fig. VII is a detail sectional view taken on line VII VII, Fig. IV. Fig. VIII is a detail perspective view of one of the draft-rod carriers.

1 designates the main sills, and 2 the subwhich my rigging is applied.

3 is the end sill, fitted to the ends of the main and sub sills.

4 designates the body-bolster, fixed to the sills 1 and 2, and 5 is the truck-bolster, on which the body-bolster is mounted.

6 designates draft-rodcarriers, mounted in to the sills 1 and 2 by bolts 8, that pass vertically through the carrier-wings 7 and the sills to which they are fitted. Each of the carriers 6 has an upwardly-extending tongue tween said carriers and the sills.

9, that fits between the sills 1 and 2 and is held by the transverse bolt 10, passing therethrough and through the sills. On the forward end of each tongue 9 is a stud 11, that enters a recess in the rear face of the end sill 3 (see Fig. II) and prevents lateral movement of the carriers and sills. On the upper face of the carrier-wings 7 are ribs 12, that fit in recesses in the lower faces of the sills 1 and 2 and serve to strengthen the connection be- Each carrier 6 is provided with a box 13, located at the under side thereof and containing pockets 14. (See Fig. II.) Each of the carriers 6 is tapered at its outer end, as seen at 15, Figs. II, IV, and VIII, and contains a noncircular cavity 16, to which more particular reference will hereinafter be made.

17 designates draft-rods mounted in and extending through the pairs of draft-rod carriers 6 and having mounted thereon draftsprings 18, that occupy the pockets 14 in said carriers.

19 is an equalizer located beneath the sills 1 and 2 and having bores extending therethrough, through which the draft-rods 17 pass. At the sides of said equalizers are bosses 20, that enter the pockets 14 in the draft-rod carriers and bear against the draftsprings 18. (See Fig. II.)

21 designates the draw-bar, provided with the draw-head coupler 22. The draw-bar is rockingly mounted in a stirrup 23, suspended beneath the end sill 3-by bolts 24, and seated on said stirrup is a chafing-plate 25. Within the stirrup 23 are saddle-blocks 26, that bear against .the sides of the draw-bar 21 and are held by bolts 28, that pass vertically through said stirrup and the chafing-plate 25, as seen in Figs. V and VI, this construction being adopted to permit free rocking motion of the draw-bar. The free end of the draw-bar 21 is slotted, as shown in Fig. VII, and mounted in the slot therein are antifriction-rollers 29 and 31, adapted for rotation on their pivotpins 30 and 32, the roller 29 being positioned in front of the equalizer 19 and the roller 31 being positioned in the rear of said equalizer. One of said rollers is of greater diameter than the other, that 29 being shown in the drawings of the greater diameter, and they are interchangeable, so that their positions may be reversed in order that the draw-bar may be moved inwardly or outwardly to suit exigencies, according as greater or less projection of the draw-bar coupler may be desirable or necessary. To illustrate, if the draw-bar coupler is to be projected to the greatest extent the rollers are positioned, as shown in the drawings, with the roller 31 at the rear of the equalizer, whereas if it is desired to obtain the least projection the rollers are reversed, so that the larger roller 29 is.positioned at the rear of the equalizer. This arrangement is of merit in connection with the natural wear of the parts, inasmuch as the rollers can be reversed at any time to suit conditions.

33 designates a swing-bar having in its forward end an open slot 34: and pivotally mounted in a slotted hanger 35, that is fixed to the car-sills l and 2. The forward slotted end of the swing-bar 33 is fitted to the bolt 32, seated in the rear end of the draw-bar, so as to have rocking connection therewith and at the same time be of ready disconnection from the draw-bar. The swing-bar 33 extends rearwardly from the hanger 35 and is connected to the truck-bolster 5 by links 36 to provide for the communication of motion from said bolster to said swing-bar.

The purpose of taperingtheouterends of the draft-rod carrier-boxes 13 at 15, as hereinbefore mentioned, is to provide an inclined surface at the front ends of said boxes, which will permit of the boxes riding upwardly onto the draft-rigging at the facing end of an adjoining car in the event of a collision, so that said boxes and the carriers equipped therewith will not be broken or severed from connection with the sills to which they are attached. The carriers 6 are all of the same construction, being tapered at their ends, so as to be interchangeable, and in order to provide for the mounting of the draft-rods 17 therein it is necessary to utilize means assembled with the rear carrier boxes 13, against which the nuts of said draft-rods may have bearing. This means I provide by the introduction of filler-washers 37, one of which is shown in detail in Fig. III, the said Washers having a flat outer face 38 and a tapering inner face 39, corresponding in shape to the taper 15 of the carrier-boxes. Each washer has a non-circular protuberance 40, that is adapted to fit in the non-circular cavity 16, contained by a box 13, so that the washers will fit snugly to the ends of said boxes and be prevented from rotation therein, while presenting the flat face 38 for the bearing of the nuts of the draft-rod 17, in order that said 11 uts may be readily turned on said draft-rods.

In the practical operation of the draft-rigging any movement of the truck-bolsters 5 is communicated, through the links 36, to the swing-bar 33 and therefrom to the draw-bars 21, so that said draw-bars will swing correspondingly to the movement of the truckholster and always maintain the draw-bar coupler-heads in connection with each other between the adjoining cars of a train irrespective of the contour of the track on which the truck-wheels of the cars travel. The slotted inner end of the draw-bar swings freely on the equalizer 19 and continues this engagement with said equalizer through the medium of the antifriction-rollers 29 and 31, whereby connection to the draft-rods 17 and the draft-springs 18 is continually maintained to exercise the functions of said parts.

' I claim as my invention- 1. In a draft-rigging, the combination with the car-truck and the car-body, of a drawhead adapted for swinging movement,a swingbar pivoted to the car-body and connected to the rear end of the draw-head, and connections between the swing-bar and the truck to control the movement of the draw-head, substantially as described.
